N EC K-YOKE.

SPECIFICATION forming part of Letters Patent No. 441,538, dated November 25, 1890.

Application filed August 1, 1890.

To all whom it may concern:

Be it known that we, CHARLES EDWARD DAVIS and CHARLES LEwIs, of Neosho, in the county of Newton and State of Missouri, have invented a new and useful Neck-Yoke, of which the following is afull, clear, and exact description.

This invention relates to an improvement in neck-yokes for draft-animals, the objects tions of parts,which are hereinafter described,

and indicated in the claims.

Reference is tobe madeto the accompanying drawings, forming a portion of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the neck-yoke closed. Fig. 2 is a longitudinal section through the axis of the device shown in Fig. 1, with one end extended; and Fig. 3 is a plan view, partly sectional, of a modified form of construction that is adapted for light vehicles.

In Figs. 1 and 2 the device shown is preferably supplied for use in connection with heavy wagons or carriages, and is comprised of a central socket-piece A, which isthreaded internally at each end for the connection therewith of two tubular cylindrical yoke-sections B, preferably made of wrought-iron pipe of proper diameter and length, threaded externally at one end to engage the socketpiece A.

In the outer ends of theyoke-sections B the thimbles a are screwed, these parts being threaded internally and externally to permit the removable connection of the thimbles with the yoke-sections, as shown in Fig. 2. The thimbles a have their interior diameters equal and necessarily align with each other from their position in the sections B.

In each yoke-section B a tubular extensionpiece C is inserted, the external diameter of said pieces 0 being proportioned to the 1nternal diameter of the longitudinal apertures Serial No. 360,646. (No model.)

in the thimbles a, so that the extension-- faces 'of the extension-pieces O elastic spiral coils E are placed, which are made of spring wire of such a gage as will admit of the free' insertion of the coils within the yoke-sections B if the thimbles a are removed. On the inner ends of the extension-pieces O internallyscreW-threaded caps 12 are mounted, these engaging the threaded ends of the pieces 0, as represented. The outer diameters of the caps b are the same and should be such with relation to the inner diameter of the. yokesections B that they will freely slide therein. If the thimbles a are removed from their positions in the yoke-sections B, and the spiral spring-coils E placed on the yoke-extension pieces 0, and the parts assembled, as shown in Fig. 2, the thimbles a being replaced, it will be evident that the resilience of the springs will hold the extension-pieces 0 normally retracted within the extension-pieces, as represented in the left-hand end portion of the yoke shown in Fig. 2.

Upon the outer ends of the extension pieces Othe caps c are secured by a threaded engagement with the ends of these pieces, and each cap has a swivel-eye d attached to its side, said eyes having the rings e loosely connected with them.

Near the longitudinal center of the socketpiece A there is a ring D, connected by swivel eyes or rings f, which ring is adapted for a convenient connection of the neck-yoke to a vehicle-pole, while the rings 6 are engaged by straps (not shown) that lead to the collars on the animals. In Fig. 3 the socketpiece Ais dispensed with and a short center piece of pipe F substituted for it, this pipe having such a relative diameter to that of the yoke section B that the externallythreaded ends of the pieceF may be inserted into the tapped ends of the yoke-sections, as shown. Around the center piece F there is a metal or leather hanger G, secured by any proper means, its integral projecting endportion g having a ring form for aconnection of the yoke-coupling to the pole and breast straps of the team of animals in the usual way.

In use this improved neck-yoke will yield readily to pressure on its ends and automatically resume its normal length, which will enhance the comfort of the animals it is attached to, as the whipping of the pole will not injure them, and if it is necessary for one or both of the attached animals to move sidewise to escape contact with a mud-hole or an obstruction in the road the construction of the yoke will admit of such movement and by its retractile power again resume a correct length for ordinary travel and lateral guidance of the team.

Having thus described ourinvention, what weelai-m as new, and desire to secure by Letters Patent, is-

1. A neck-yoke consisting of a center piece provided with ,a pole-ring, two tubes 13, having a screw-connection at their inner ends with the center piece and internally threaded at their outer ends, the externally-threaded thimbles a, screwed into said outer ends, the extension-tubes O, passing through said thilnbles and having screw-caps Z) on their inner ends snugly fitting the bore of tubes B and screw-caps c on their outer ends, each provided withapole-strap connection, and springs surrounding the tubes (1 and abutting at their ends the ends of caps b and thimbles a, substantially as set forth.

2. A neck-yoke comprising a center piece F, externally threaded at its ends, the tubes B, screwed at their inner ends upon the ends of said center piece, a strap G on the center piece between the inner ends of said tubes and having a pole-ring g, the thiinbles a in the outer ends of the tubes, the tubes 0, passing through said thimbles and having screwcaps b c on their inner and outer ends, respectively, the outer caps 10 eing provided with eyes, and the springs surrounding the tubes (1 and abutting at their ends the ends of the caps b c, substantially as set forth.
